I scored a sample of how a programming event communication should look like without errors.
It turned out that $18 is tside during programming. Did you managed to figure how the obd2 messages are transfered to eside.
The only elm device that can do the job is the obdlink devices. They have big enough buffer to handle reading/writing. They don`t support high speed mode x4 so it is still unclear if they will work in x1 mode with that flash routine.
